Specification of Letters Patent.

Patented Nov. 19,1912.

Application filed August 10, 1911. Serial No. 643,465.

To all whom it may concern Be it known that I, Pinnnn BARNES, a citizenof the United States, residing at Seattle, in the county of King andState of Washington, have invented certain new and useful Improvementsin Cars for Monorailways, of which the following is a specification.

This invention relates to cars designed for use on elevatedmonorailways.

The object of the present invention is the perfecting in such cars and,more particularly, to improve the trucks therefor and the manner inwhich the same are connected with a car body.

The invention consists in the novel construction and adaptation ofdevices which will. be hereinafter described with reference to theaccompanying drawings, wherein Figure 1 is a horizontal. sect-ionshowing a portion of a monorail car embodying my invention. Fig. 2 is alongitudinal vertical section taken through 2-2 of Fig. 1. Fig. 3 is atransverse vertical section on 3-3 of Fig. 1.

The reference numeral 5 designates a track rail desirably constructed ofwood, and is suitably supported as by posts 6. The car body 7 is formedwith a centrally disposed trunk 8 extending longitudinally of the carfor the accommodation of the trucks and of the track-rail 5. Said trunkis secured to, or made a part of, the underframing of the car. Asillustrated, this underframing comprises two longitudinal beams 9carrying horizontal transverse bars 10 and from the ends of the latterdepend frame members 11 which extend down to and under the car floor 12at opposite sides of the track.

Adjacent to their ends, the beams 9 are connected to body bolsters 13which are pro vided at their centers with sockets for king bolts 14 andnear their outer ends are desirably provided with apertured lugs toserve as journal bearings for the axles of rollers 15. Each of thetrucks is provided with a relatively large car wheel 17 provided withside flanges 18 which serve to prevent a wheel from being displaced fromthe track in either lateral direction. In advance, desirably, of suchwheel, each truck is provided with a pivot wheel 19 which, in thepresent disclosure, is illustrated as being unprovided with flanges. Atruck also is provided with a pair of guide wheels 20 disposed to rotateon vertical spindles 20 and, upon occasion, track against the oppositesides of the rail 5.

These guide wheels are disposed at distances apart to ail'ord a smallspace between their peripheries and the rail when the associated wheel17 is traveling centrally of the track and upon a straight portionthereof. A truck-frame is provided with columns 21 between which are theboxes 22 for the journals of the axle 17 of the wheel 17. 23 are thecolumns of the boxes 24: for the axle 19 of the pilot wheel. Upper andlower side bars 25 and respectively, connect the columns 21 and 23, and27 is an end piece connecting the side bars 26 to furnish strength andrigidity to the truck-frame suiiicient to withstand lateral strainsderived from the forces encountered by the guide wheels 20 when engagedwith the track-rail.

28 indicate pedestals secured to the bars 25 above the columns 21 tosupport the ends of a truck-bolster 29. Centrally of the truck-bolsteris a socket for the king-bolt lt and a turret 32 on the truck bolster isprovided to fit into a recess provided in the underside of the companionbody-bolster. The truck-bolsters are provided with side bearings 30 uponwhich the rollers 15 are supported.

31 represent tie-bars extending from the top of the pedestals 28 to thebars 25 in proximity to the pilot wheel of each truck.

The axis of the king bolt, or the swivel connection of the truck, islocated between the axes of the wheels 17 and 19 thereof, but ispositioned closer to that of the wheel 17 in order that a load placed ona truck is borne principally by the wheel 17 and with. only sutlicientweight applied to the other wheel 19 to insure the same tracking on. therail. By thus subjecting a pilotwhecl to a relatively light load theresistance to lateral movement will be correspondingly small and thus atruck is easily influenced by the wheels 20 to serve the wheel 19 uponentering or leaving a curved portion of a track.

The side bearings, provided in the illustrated embodiment withanti-friction rollers 15, tend to maintain the body bolster and carstructure connected therewith against side tilting with respect to thetrucks.

The operation of the invention will, it is thought, be understood fromthe foregoing description.

lVhat I claim, is

1. The combination with a monorail, and a car body, of a car trucktherefor comprising a frame carrying a car wheel and a pilot wheel whichtrack on the top surface of said monorail, a pair of guide wheelsdisposed in proximity to the pilot wheel and arranged to track againstthe opposite sides of the monorail, and a swivel connection for thetruck frame disposed relatively close to the car wheel whereby the truckis adapted to turn on a vertical axis at a closer dis tance from theaxis of rotation of the car wheel than from the axis of rotation of saidpilot wheel.

2. The combination with a monorail, of a truck provided with a flangedwheel arranged to travel on the monorail guide wheels carried by thetruck and adapted to track against the opposite sides of the monorailfor regulating the direction of travel of the flanged wheel, and asupplementary wheel arranged to travel on the monorail 20 and serving tosupport said guide Wheels.

3. The combination of a monorail, and the frame of a car, a truck frameconnected with said frame for rotary movement about a vertical axis, twotraction wheels for the 5 truck frame, and a single pair of guide wheelsengageable with the sides of said monorail whereby the turning of thetruck about the aforesaid axis is controlled.
